choose the number of days then go to as many activities as you can fit in. For a newby, I'd suggest the Snowbird Tram, Olympic Park, one of the 2 main gardens (Red Butte or Thanksgiving Point), then pick others depending on ages & interests of group. To give an idea of savings, just the Snowbird tram is $40 so for 2 days is around $60). You could take the back way to Provo up to Park City then across to Heber City & down Provo Canyon. Take little stop @ Bridal Veil Falls in Provo Canyon & maybe a couple miles off side to see Sundance.
Provo is mostly casual & semi casual dining. Lots of ethnic & typical college town foods. Gotta try the Creamery for BYU ice cream.
